التوازن البيئى: أسباب اختلال التوازن البيئى

The video explores the era when extraordinary creatures ruled the Earth, sky, and seas for over 118 million years. It describes the diversity of these creatures, from massive, train-sized beasts to small, chicken-sized predators and giant herbivores. The narrative takes us back 220 million years to a time when Earth was a single landmass known as Pangaea, shaped by climate changes. Around 215 million years ago, a mass extinction event wiped out over 90% of life, possibly due to a stellar explosion or asteroid impact. As the planet slowly recovered, reptiles emerged as dominant species.
